One of the most commonly found puffers and a fin nipper. I wouldn't recommend this puffer to a beginner, I would recommend a Figure 8 better. Can be a killer and will pick on fish with long fins. Often describe as cute and is more shy then the Figure 8. Will be more agressive when older. They enjoy lots of structures in there tank like rocks and bogwood. If you want tank mates for the Spotted I would recommend fast moving fish, no tank mates with long fins.
